Fire on a Moonlit Night

Seven years ago, Frost City was rocked by the “Frost Night Serial Murders.” White chrysanthemums, red spider lilies, and henbane flowers left beside each victim were the killer’s taunts, but the case eventually went cold. Zhang Yunsheng was still a rookie then. He followed his mentor, Jiang Chongshan, in pursuing the case to the very end, but was left with nothing but regret. Seven years later, a woman’s body is found in an abandoned building in the old district. The hemp rope, iron nails, and eerie knots are exactly like those in the old case, except the killer’s signature flower is missing and strange needle marks have appeared on the victim’s arm. He thinks the killer has returned, but as he investigates, he discovers it may all be an elaborate copycat murder. His mentor’s silence on the phone, the worry in Lin Wanzhou’s eyes, the witness’s hazy account, and an old photograph showing the earring of a victim from seven years ago... As the layers of fog lift, Zhang Yunsheng realizes that the unsolved case from seven years ago wasn’t the only thing left behind: the truth was deliberately buried, too. And what he is pursuing now isn’t just a killer, but an obsession and a chance at redemption that have bound him to his mentor and Lin Wanzhou for seven years.
